Document Summary
Energy alternatives: nonrenewable: oil and natural gas (petroleum), coal, alternative fossil fuels (tar sands, oil shales, shale gas), nuclear energy (because once you, renewable/replenishable/inexhaustible: biomass energy (fuelwood, ethanol, energy-from-waste), hydropower, solar energy, wind energy, Geothermal energy, tidal and wave energy, chemical fuels (e. g. , hydrogen) have split an atom, you can"t put it back together(cid:524: (ydropower, nuclear, and biomass are (cid:498)conventional(cid:499) energy alternatives. Fuelwood and other biomass sources provide ~(cid:883)(cid:882)% of the world"s energy, hydro each account for nearly one-sixth of the world"s electricity generation: modern hydropower uses two approaches. Hydroelectric power uses the kinetic energy of moving water to turn turbines and generate electricity. Approaches (first is much more common): 1) dams harness kinetic energy by storing water in reservoirs (cid:498)impoundment(cid:499) approach (disrupts more than. 2nd approach)) 2) run-of-river generates energy without greatly disrupting the flow of river water nuclear power ~6. 3%, and hydropower provides ~2. 2%.
